My teacher wants me to write a research essay about stem cells and potential ethical limits. The paper is going to be divided into four parts.
Intro, pros, cons, and the limit. I have my sources and I can’t change them. I also have my quotations and I can’t change them but you can take some of them out or re-arrange them if you need to but you can only use the quotes I have. I will have my teacher’s instructions and the document I will have you work on in the link below. I already formatted it in the way my teacher wants the paper.
